Cryptographic analysis demonstrates fast attribute-based encryption for conditional access systems, suggesting pathways to overcome real-world deployment bottlenecks.
Time and again, attribute-based encryption has been shown to be the natural cryptographic tool for building various types of conditional access systems with far-reaching applications, but the deployment of such systems has been very slow. A central issue is the lack of an encryption scheme that can operate on sensitive data very efficiently and, at the same time, provides features that are important in practice.
